Sometimes called ‘male sterilisation’, vasectomy prevents pregnancy by cutting, tying or blocking the tubes that allow sperm to pass from the testicles and out of a man's body through the penis. Vasectomy needs a small surgical operation. This is now frequently done under local, rather than general, anaesthetic.

Vasectomy offers no protection against sexually transmitted infections.

How long does a vasectomy last?

Vasectomy is permanent and should only be considered by men who do not want to have any children in the future.

It can be reversed but it doesn’t always work and vasectomy reversal is not usually available on the NHS.

How effective is a vesectomy?

The lifetime failure rate is about one in 2,000. This means that one out of 2,000 men who are sterilised will get a woman pregnant during the rest of his lifetime.

Where can I get a vasectomy done?

Vasectomy needs a small surgical operation. This is now frequently done under local, rather than general, anaesthetic. Your GP or sexual health clinic can arrange this for you.
